The short answer is 'yes.' The feasibility answer is that with sufficient funding and space, anything can be filtered, although neutrinos may be a practical exception. Most industries that require clean water at some level of purity will acquire a filtering system, tailored for the incoming and desired outgoing water chemistries and needed flow rate. For example, large reverse osmosis systems exist for laboratory and factory use. Last I looked, Spectrapure had some images of such equipment on their web site. I'm sure that there are others. Semiconductor fabs (plants) require extremely pure water.

For cost sake, however, certain household uses such as toilet flushing might not deserve the cost associated with including them in the pure water plumbing if a separate line can be installed. Bathing water or laundry water may or may not need filtering depending on what is in the water. Filtering the garden hose faucets, or a feed to an irrigation system might also be excluded.

Specialists in this area will need to know the chemistry of the source water and the desired chemistry of the filtered water. Some chemicals can be removed with only charcoal filters, while others may require reverse osmosis or other methods I'm not familiar with.

Well, that's a little dismal, Kas. We've had members who had whole house R.O. systems. It's expensive, and only useful if the water really isn't suitable for showering and laundry, but some have done it. If it's really only drinking/cooking water that you're concerned with, putting a small unit in the kitchen might do you. You can put water jars in the bathrooms for tooth brushing, and pitchers in the entertaining areas. Or even three or four small units, which could be more cost effective in a big house than a whole house unit. When you're pricing, don't forget to figure in the cost of filters.

My house came with an R.O. at the kitchen sink, which was great, because we used to have really nasty tasting (though perfectly safe water). The annual filter replacement was about $100, which was fine. Then it needed a $500 every five years filter and I said no. The water company had much improved the tap water.

S, if you google the subject you can find some to start reading up on. What's required at your house is going to be pretty ideosyncratic, and require some testing of your water. It's also worth thinking about maintenance. Unless you're good at plumbing and mechanics, and want to learn everything about your system and how to repair it, you'd do well to confine your search to what's available in your area, including quality maintenance.

Thank you so much for the thoughtful feedback. Specifically, I am wanting to filter water that comes through the sinks, bathtub and showers. I hadn't thought of the maintenance required with buying filters, but that is something to consider. Thank you both!

I had a filter+charcoal system installed on our house several years ago. All the house water is filtered to my choice of either 5 microns (cheap) or 1 micron (expensive).. Then we had the charcoal filter plumbed to only supply drinking water at the kitchen sink (just the cold water side of the faucet and the in-door dispenser of the refrigerator). That required a plumber to set up a manifold in the garage, with several valves. I believe there are now do-it-yourself kits available. I get my filters on-line at Aqua Pure, I believe. I don't currently have a refill or I would look up the brand/models for you, but you can just google it. I try to change the cartridges every six months.

We have an aqua pure whole house filter, but only the kitchen, and an outdoor faucet (outside the kitchen wall, by the deck) are plumbed through it. We had it installed when we reno'd the kitchen; cold water lines running up to the fridge, pot filler faucet, and sink (the outside faucet taps into the sink faucet pipes).

We replace the filters twice a year, APS117 ("S" indicates it is the sediment filtering replacement filter).

We lived in a home that was on hard well water. The iron content was awful. If you don't treat the water, it will eat through pipes, appliances and your body. To treat for this, we installed a whole house softener and filter. It tasted crappy but it was safe to shower and brush your teeth with it.

At the kitchen sink, we installed an RO system. We drank and cooked using that water. The water from the RO system was tasty.

It sounds like a pain, but you will adapt to life with one. The main system worked with a brine solution. Bags of rock salt were needed. It was pretty simple to maintain.

I suggest you call a larger company such as Culligan and have a salesmen come out, conduct a test and give you the sales pitch. It will be free and you will learn a lot.

Ask your neighbors, there may be a local company that uses other brands of equipment. We've used both. We were happy with both.
